Answer
(a) $f(2)=1$
(b) $f(-1) = 7$
Work Step by Step
(a) The value of $f(2)$ is the range element paired with the domain element $2$.
The domain element $2$ is paired with the range element $1$.
Thus, $f(2) = 1$.
(b) The value of $f(-1)$ is the range element paired with the domain element $-1$.
The domain element $-1$ is paired with the range element $7$.
Thus, $f(-1) = 7$.
